Dinteloord aquifer storage and recovery (ASR) scheme further expanded to 960 cubic meters per day

As announced earlier this year, the Dinteloord ASR-Coastal replication site was further expanded this summer. After realizing a second ASR-well in October, a third and fourth ASR well were realized in April 2017. All four ASR wells were connected to the ASR infrastructure and put into operation since early September. Since then, high-quality irrigation water is produced from the effluent of the nearby sugar factory using a combination of UF and RO and infiltrated in a local sand aquifer.

In 2016/2017, a total of 25 000 m3 was stored and recovered. With the current infiltration rate of 960 m3/d, it is aimed to store almost 150 000 m3 by the end of January. This is when the sugar factory stops its production and effluent is not available for irrigation water production anymore. Based on a recently updated water balance , this should be enough to supply water users in the event of an extreme dry spell in 2018. To meet the demands after 2018, the ASR capacity will be doubled in the coming year. In the last year of the Subsol project, the performance is of this expanded ASR scheme is monitored.
